## Physical Fire Testing & Engineering Verification
- **CSIRO Mogo Full-Scale Flame Immersion (FE2828Rpt3 Rev D)**: Full-scale destructive burnover testing exceeding 1,000°C+ (peak 1,024°C). Internal cabin air temperature remained below 30°C throughout the 60-minute test.
- **CSIRO Mogo 29 kW/m² Radiant Heat Exposure (FE2828Rpt2 Rev E)**: Verified passive thermal barrier attenuation and door seal integrity with tenable interior air quality (O₂ > 18%, CO₂ < 2.5%, CO < 30 ppm).
- **Falling Timber Impact Resistance (Bomen Report)**: 500kg log drop test onto roof structure confirming zero penetration and door operability post-impact.
- **Engineering Peer Reviews**: Supported by independent Fire Safety Engineering peer review and Chartered Structural Engineering computations for ABCB Performance Standard (2014) / BCA H7P6 assessment.

## Statutory & Regulatory Compliance
- Class 10c private bushfire shelters have no Deemed-to-Satisfy (DtS) recipe in the NCC; every installation requires a building permit assessed as a Performance Solution by a municipal building surveyor or accredited certifier.
- Standard siting requires a minimum 6.0-metre clear defensible setback from dwellings and unmanaged combustible fuels, placed on a 150mm reinforced concrete slab or 200mm compacted crushed-rock pad (100 kPa bearing capacity).
- A private bushfire shelter is an emergency refuge of last resort; it does not guarantee survival and is not a substitute for early evacuation.
